Guide to the IEEE Std 1547-2018 and Its Impact on Cooperatives
Written for cooperative engineers, this "field guide" to the Institute of Electrical and Electronics Engineers Standard 1547-2018 (IEEE Std 1547-2018) was written by the National Rural Electric Cooperative Association (NRECA) as a starting point with the new standard.
Guide to the IEEE Std 1547-2018 and Its Impacts on Cooperatives (Ropp 2019)
The guidance provided in this resource from NRECA is intended for cooperative engineers
seeking information on the recent changes to IEEE Std 1547-2018, its requirements,
and potential implications for cooperative electric utilities. This NRECA guide is
not intended be an all-inclusive guide to, nor a replacement for, the standard. While
this guide was developed to assist cooperatives, any stakeholder or engineer may benefit
from this approach which relates IEEE Std 1547-2018 to the potentially familiar 2003
version of the standard.
Topics Covered
The intent of the NRECA guide is to aid cooperative utilities with the adoption of the standard by:
- Providing a brief overview of the changes and new features of the standard compared to the 2003 version of the standard
- Discussing options for setting voltage and frequency trip functions that closely approximates the values in the 2003 version (i.e., settings that most closely maintain a "business as usual" scenario)
- Identifying what settings or features are now mandatory and cannot be disabled
- Highlighting the clearing times and thresholds if the default settings are utilized.
Key Takeaways
Bridge from 2003 to 2018
For engineers and technical stakeholders that are familiar with the 2003 version of the standard, this guide provides key and important differences to the new standard, including technical capabilities and functional settings.
Context of the Authority Governing Interconnection Requirements
According to this guide, the responsibilities of authority governing interconnection requirements for a co-op likely rests with the cooperative's governing board. In some cases, requirements for certain functions that impact bulk power system reliability (e.g., ride-through) may be set with input from the cooperative's generation and transmission provider, as well as the regional reliability coordinator.
